IMPROVEMENT IN FURROWING-PLOWS.

Specification forming part of Letters Patent No. 122,284, dated December 26, 1871.

We, ABRAHAM P. ROHRER, GHInsTIAN F. ROHRER, and J oHN H. BLosE, all of the county of Clarke and State of Ohio, have invented certain Improvements in Furrowing-Plows, of which the following is a specification:

Ourinvention relates to that classof furrowing or marking plows which are mounted on wheels and make several furrows at the same time.

The firstpart of our invention consists in ahinged or pivoted frame in combination with the axle and wheels of a riding-plow, said frame being pivoted on a rod of iron on the back of the axle, and runnin g parallel with the same, in connection with the front ends of the plow-beams, the object of this part of our invention being to raise and lower the back portion of the frame and the plows attachedthereto by shifting the weight of the driver to the front portion of the frame, forward of the rod or fulcrum point on which the frame is pivoted in turning the machine at the ends of the furrows. The second part of our invention relates to a peculiar construction of parts attached to the back rail of the machine; and consists of vertical guide-ways at the rear ends of the plowbeams, in which they are allowed to move freely up and down as the plows pass over uneven ground, a spring-catch or stop preventing the plows from being raised too high, which can be operated by the foot of the driver when it is de sired to release the plow and raise it above the level of the frame. Each plow is operated independently. The object of this part of our invention is to allow any one of the plows when meeting an obstruction to be raised up so as to pass over it. Another part of our invention consists in an adjustable seat, made in three parts, the middle portion hinged at one end to permit it to be thrown back, so that the middle plow-frame can be raised up to a sufficient height, through the opening made by the middle seat-board, to cleara stump or stone. It is made to slide toward the axle or back to the rear of the frame to regulate the weight of the plows to suit the different depths of furrowing required.

Figure l is a side elevation of our machine. Fig. 2 is a plan of the same. Fig. 3, Sheet 2, is a section of the left end of the back rail of frame with a portion of the seat-rail and seat attached, as seen from the front, the dotted lines showing the middle portion of the seat partly raised. Fig. 4 is a side elevation of one of the plow-beams, a

section of the standard; also, a cross-section of the back rail of frame, showing the parts which control the raising and lowering of the plows. The dotted lines represent the parts when raised.

In Fig. l, A are the wheels, B the tongue, 0 the main frame. ais the axle; a, therear rail of frame 0. b is the front part of the frame, which extends forward and upward at an angle over the axle of the machine. 0 is the foot-board on front frame I). ()n this the operator steps his foot, throwing his weight off the main frame 0 onto the front, forward of the pivot-rod or bar 1", thereby raising the main frame with its attached plows clear of the ground when turning at the ends of furrows. The front part can be held down, when tilted forward, by the slide i, which is fastened on the top of footboard b, it being passed through the loop j on the tongue, this loop passing up through the slot 1', Figs. 1 and 2, in the foot-board. The frame is held up in this manner when the machine is on the road or going from one field to another. A retaining-chain, n, shown in Fig. 1, to graduate the height to which the frame is raised, is used. The lower end of this chain is attached to the tongue and the loose end hooked over It, a hook on the front of foot-board b. (See also Fig. 5.) This chain is left off in Fig. 2, in order to show the position of loop j on the tongue in this figure. The cap rails c on the-uprights c of thefront frame answer as a support for the driving-reins. d is the seat, the middle part cl, shown in Figs. 2 and 3, being hinged at f. In Fig. 3

this part is shown in dotted lines partly raised. Seat d is strengthened by braces cl bolted across the angle formed by the board and standard. 0 e are transverse braces, their rear ends bolted to the plow-beams 6, their forward ends pivoted to bar or rod 7, in connection with the frame and front ends of the plow-beams. f are hinges to sections of seat-board d and d. (See Figs. 2 and 3.) Seat 11 is held in place by the pin t, which is passed through the slide plates on lower part of its standard, and throughthe holes t made in seat-bar, for adjustment to regulate weight of driver on the back frame and plows, theseat being moved backward or forward on theframe bars, as required. m are bent rods, looped on the top of and in line with the plow-beams, their object being for catching hold of with the hand in raising the plows. Theseloop handles extend along the tops of the plow-beams, so that they can be readily grasped by the hand at any point when the seat is shifted. The plows'are raised, so that the rear ends of their beams shall clearthe guide-ways s and springcatch 8 on the rear frame-bar a. When necessary to raise any one of the plows over an obstruction, as a stump or stone, or to clear it of weeds or trash, the operator presses back the spring-catch s with his foot, and grasping the loop-handle m raises the plow. (See the dotted lines, Fig. 4.) The rear rail a is cut through at the rear of the plow-beam e, between the guide-ways s, in Fig, 4, to show the location of spring-catch s, and the slot in which it playsin the rail. The plate 0 is made in one piece with the part which passes around the rear end of the beam of the plow, (see Figs. 3 and 5,) its'depending portions forming the fork in which the top of the plow-standard h is pivoted. Braces 1), flexibly attached at their upper ends to-ring-bolts on the under side of the plow-beams, pass through the standards to support plows p. The pivot-rod or bar 4" is secured to the axle of the machine by strong eye-bolts through which it passes, as the entire weight of the frame, plows, and driver is thrown upon this rod in operating the machine by tilting the frame.

In the model and drawing our machine is represented with three furrowing-plows; these are placed about three and a half feet apart, the

spaces between the outside plows and the wheels being about one foot and nine inches, so that the wheels will track between the furrows.

We do not confine ourselves to three plows, but use two or more, though in using as many as three much more ground can be prepared for planting than with a less number, and the labor of operating the machine is but little more. I I

The construction of our machine forward of the axle-4. e., tongue, braces, &c.does not difier materially from other riding-plows.

The advantages of our machine for furrowing any depth required for planting, and in all kinds of ground where a riding-plow can be operated, are easily seen. The mechanism of the frame and parts for raising the plows altogether and separately is simple and easily operated; no matter at what point on the frame the seat may be placed the plows can beoperated with ease and certainty. r

We do not claim the attachment of the cultivator-frame to a wagon axle-tree by means of pivoted levers, connecting-rods, &c.', as the same has been before used; but

We claim as our improvement in furl-owingplows- I 1. The arrangement of the pivoted orbalanced frame 0, projecting frame I), foot-board b slide 'i, slot 1" and loop j, as shown and described,as and for the purpose set forth.

2. Spring-catch s, guide-plates s, and plates 0, arranged and combined with back rail a,- plowbeams e, and handles m, substantially as shown and described, as and for the purpose hereinbefore set forth.
